Abstract

PURPOSE:To realize a casing structure for an electronic device that makes it possible for each shelf unit to obtain an ideal naturally air-cooled state which is not affected by heat from another shelf unit and that can prevent warm air from leaking due to the opening of a front door of the casing and can eliminate an unpleasantness when a body directly feels this warm air. CONSTITUTION:A plurality of shelf units 4 are arranged at predetermined intervals one on top of the other in a casing 1. Each radiator 13 is positioned between the shelf units 4 within the casing 1 and is provided with a guide plate. A spacing is formed with the upper and lower ends thereof open between a front panel 5 having a control panel and a back board 6. Consistent spacings having the same dimension are successively formed one on top of the other in the form of a chimney by the repetition of the radiators 13 and the shelf unit 4.
